Question

我在所有窗口上运行了XQueryTree，并且从数组顶部的最顶部到数组底部的最底部以z顺序获取它们。

然后，我只过滤了每个XGetWindowAttributes上显示的内容，如果它不是map_state IsVisible，则将其删除

对于每个可见窗口，我检查并获取_NET_WM_PID，_NET_WM_NAME，x，y，height（height + border_width），和width（作为width + border_width）。

我的数据就在这个要点上，也在底部：https://gist.github.com/Noitidart/94562d08f243cd7ca7ec

我的设置是两台显示器。这是他们俩的完整画面：

每个显示器上都有一个透明窗口，即显示器的高度和宽度，它们的标题是＆＃34; nativeshot_canvas＆＃34;。

通过查看数据，我发现XQueryTree窗口被分成多个条目。我的手动分析告诉我：

＆＃34; nativeshot_canvas＆＃34;在左侧监视器上
＆＃34; nativeshot_canvas＆＃34;在右侧监视器上
- UNKNOWN WINDOW 1
- UNKNOWN WINDOW 2
水平菜单栏
左侧监视器上的水平菜单栏
右侧监视器上的垂直停靠
左侧监视器上的垂直停靠
- UNKNOWN WINDOW 3
＆＃34; Javascript Application＆＃34;窗口
＆＃34;浏览器控制台＆＃34;窗口
＆＃34; Mozilla Firefox＆＃34;带有两个标签的窗口
＆＃34;桌面＆＃34;

数据图表和我的手动分析如下。

问题

有没有办法以编程方式识别哪个条目与单个窗口相关？在我的手动分析中，我使用了一些我提出的模式，每个窗口组都以_NET_WM_PID（下面的数据为pid键）或_NET_WM_NAME（title开头。关键数据如下）。我不认为这是一个很好的模式，因为我们看到顶部有一个PID，但它们的宽度和高度都是1.

编辑：仍然坚持如何找到一种保证的方法将这些划分关联到窗口组中。我基本上需要得到所有窗口的所有x，y，宽度和高度，如果有人有任何输入我将是非常好的
